QED's Reference series is the penultimate range of interconnects in their extensive catalogue. Featuring an entirely new design concept, the cordage of the Reference models are designed first and foremost for low capacitance. This is because QED has identified this factor as being a significant player in the high fidelity listening experience, by retaining a low capacitance, sound signals are better looked after and allow for a more collected and detailed hifi performance.
The Reference range also utilises QED's 'Complementary Conductor Technology' to ensure a high-frequency detail, and their Analoc Technology to optimise signal integrity. All QED interconnects and cables feature a lifetime warranty, including the Reference series.
QED X-Tube XT400 Speaker Cable is one of QED’s prestigious speaker cables that really is a true piece of engineering at its best.
In combination with the X-Tube XT400, it is recommended that using QED’s unique Airloc termination will benefit sound even further due to the technological advantages Airloc has to offer. Compared to standard termination plugs, Airloc forms a cold weld bond between the QED speaker cable conductors and the Airloc plug itself, allowing no Oxygen to particles to start to diminish conductors over time – affecting sound response and quality over time. This also reduces contact resistance and helps to ensure that long-term performance is always going to get the best out of your Hi-Fi or Home Cinema set-up.
Please note, termination with QED Airloc is charged at separate prices. If in doubt, please contact us with regard to quantity or any other enquiry that you may have.
